In the food processing industry, maintaining strict hygiene and contamination prevention throughout the production process is essential. Food Grade Stainless steel tube serves as a core tubing material for transporting liquids, semi-liquids, and additives, widely used in sauces, syrups, dairy alternatives, and other food production lines due to its excellent corrosion resistance, smooth internal surface, and sanitary compatibility.
The tubes are mechanically polished to achieve an internal surface roughness of Ra ≤ 0.8 μm, with electropolishing (EP) typically applied to critical sections to enhance cleanability and resist microbial adhesion. The product meets internationally recognized sanitary standards such as 3-A SSI, ASTM A270, EN 10357, and AS 1528, ensuring compliance with food safety regulations and compatibility with automated CIP/SIP cleaning and sterilization systems, thus safeguarding equipment hygiene and product quality.
